That seems to have now worked, thanks for the help. New issue now, when adding the Drivers in, it doesn't let you add anything thats not a .inf file, Yet when the Server starts PXE booting it stops with an error, saying it can't find a .sys driver, any ideas?

On one Server where i have added the MAC into the BL console manually it works, but on another i get the follwoing error, i do not want to have to add the MAC in each time, is there away around this as well
